Hello,
I am in the process of limiting the cached area in mapcache. I am having trouble with both the restricted_extent and ruleset parameters. I first started by using restricted_extent such as "<grid restricted_extent="435567 98889 568247 259687">LyonCC</grid>". That parameter seemed to work. However mapcache returned 404 errors for any tiles outside of the restricted extent. Next I tried to use rulesets instead. The rulesets seem to have no effect, and new tiles were getting generated outside of the visibility extent.
Question 1: When we use restricted extents on a grid should MapCache return a transparent tile, white tile, or a 404 error? Can we control what it returns?
Question 2: Do I have my ruleset configured appropriately?
<tileset name="LyonBaseMap">
<grid ruleset="CountyBuffer">LyonCC</grid>
</tileset>
<ruleset name="CountyBuffer">
<rule zoom_level="1 2 3 4 5 6 7 8 9 10 11"><!-Do I need to include zoom levels?-->
<visibility>
<extent>435567 98889 568247 259687</extent>
</visibility>
</rule>
</ruleset>
Thank You!
Sincerely,
Mark Volz, GISP
